Title: Oil feedless scroll fluid machinery
Inventor: ARAI NOBUKATSU
IPC: F01C1/02
Filed: 1982-09-29
Abstract: PURPOSE:To prevent the gap between laps from increasing with temperature variation and suppress the thermal expansion of a driving shaft by restricting the axial displacement of the driving shaft by a main bearing and restricting the axial diplacement of a swirl scroll by a slidable member in no-lubrication which is installed between the swirl scroll and frame and a fixed scroll. CONSTITUTION:A swirl scroll is installed onto the eccentric part 4a of a crank shaft (driving shaft 4) through a cylindrical roller bearing 5. Said crank shaft 4 is supported by spherical bearings 6 and 7 fixed on a frame 3. Plate members 11 and 12 which are made of slidable material in no-lubrication are inserted into the groove formed on the seat surface of the frame 3 and the groove 1e formed on a fixed-scroll mirror plate 1a. Though said swirl scroll 2 is applied with a thrust force due to the gas pressure in a compressor 20 and pushed onto the crank shaft 4 side, sliding in the axial direction is permitted between the revolution surface of the cylindrical roller 5a of the cylindrical roller bearing 5 and the inner ring 5b of the bearing installed in the eccentric part 4 of the crank shaft 4.

Abstract: PROBLEM TO BE SOLVED: To prevent the malfunction of a device or the burning of film at the time of breakdown by positionally changing a light shielding means to a position where it is separated from the optical path of a light source against an energizing means. SOLUTION: When a negative mask breaks down in the midst of scanning negative film or positive film, the energizing of a solenoid by a driving device 82 is turned off, a rotary shaft 83 is reversely rotated by the spring force of a spiral spring 84, and either end of a light shielding plate 81 in a length direction comes to a position where it is opposed to the hole 51a of a supporting frame as shown by a solid line in figure, so that the optical path of a halogen lamp is intercepted. Thus, the film set on the negative mask is prevented from burning. When the device 82 breaks down and the solenoid is not energized, the shaft 83 is reversely rotated by the spring force of the spring 84, and either end of the plate 81 in the length direction comes to the position where it is opposed to the hole 51a of the supporting frame, so that the optical path of the halogen lamp is intercepted.

Title: Semiconductor laser element
Inventor: ISHIKAWA MAKOTO
IPC: H01S5/00
Filed: 1989-06-30
Abstract: PURPOSE:To improve temperature characteristic with a low threshold value by forming a SCH guide layer of a SCH structure of a superlattice in which AlxGa1-xAs and AlyGa1-y0.5In0.5P having a band cap equivalent to that of the AlxGa1-xAs are alternately laminated. CONSTITUTION:A semiconductor laser element is formed of a n-type Al0.75Ga0.25 As clad layer 1, a Ga0.5In0.5P/Al0.4Ga0.6As superlattice guide layer 2, a GaAs active layer 3, and a p-type Al0.75Ga0.25As Clad layer 4. An energy barrier is formed at the valance band, conductor of a superlattice guide layer, and electrons and holes locally exist in a potential well. Since the energy gap of a substance for forming a superlattice is the same, the wells are alternately formed in a layer growing direction, and the electrons and the holes are separated. As a result, transition probability of recombining the electron-hole pairs is reduced, and the life times of minority carriers are increased as compared with a bulk. Accordingly, reactive current to be recombined in a guide layer and consumed is reduced, and temperature characteristic is improved with a low threshold value.

Next, a laser-emitting apparatus B is set on the ground, and by scanning with an radiated beam of light from a source 3 in such a way that it diverges vertical with the specified width by a scanner 4, a light beam A provided with a width in the vertical direction is projected on to the photosensors S2, S1. Upon tilting of the vehicle V by theta deg.by rolling, light-receiving positions of the sensors S2, S1 become x2, x1 and the angle theta is calculated as tan<-1>[(x2-x1)/k]. A planting apparatus 2 is adjusted for the horizontal position based upon this angle of tilting theta.

Title: Production of silicon nitride
Inventor: FUJII HIDENORI
IPC: C01B21/068
Filed: 1995-07-05
Abstract: PROBLEM TO BE SOLVED: To produce a silicon nitride which can give a silicon nitride of high content of α-form in high yield in a shortened time by direct nitridation of metallic silicon. SOLUTION: Metallic silicon is allowed to react with a N2 +H2 or N2 +NH3 mixed gas at 1,180-1,300 deg.C. While the reaction proceeds, the concentration of H2 lowered in the reaction gas to rapidly advance the reaction, and thereby the rates of reaction and conversion to the α-form are raised and the time required for reaction is shortened.

Title: Reproducer
Inventor: NAGANO KAZUHIRO
IPC: H04N5/93
Filed: 1985-07-31
Abstract: PURPOSE:To improve the responsiveness of correction by delaying reproducing signals obtained in running period to compress them by a delaying device instead of an operation for correcting a cylinder system. CONSTITUTION:A control voltage generating circuit 10 is reset by a RF switching pulse from a line 7 and starts generation of saw tooth wave voltage therefrom. The frequency of clockpulse outputted from a voltage control oscillator 9 becomes larger in gradual correspondence to saw tooth wave voltage. Accordingly, a delay of reproduced video signal inputted to a delay line CCD 8 becomes smaller gradually, and becomes minimum at an end of 1 field. It is so selected to set the difference between delay at the starting end and delay at the terminating end to alphaHX(1/fH). Accordingly, reproduced video signals in tape running period are compressed in terms of time axis by alphaH in 1 field period compared with reproduced video signal when the tape is stopping. Accordingly, horizontal synchronizing signals in 1 field period increases incorrespondence to it and horizontal frequency becomes high.
